ATENT' JOHN L. DU BOIS, OF DOYLESTOIVN, PENNSYLVANIA.

PEN-WIPER.

SPECIFICATION forming part of Letters Patent No. 473,148, dated April19, 1892.

Application filed March 7, 1892.

To all whom it may concern:

Be it known that I, JOHN L. DU 13018, a citizen of the United States,residing at Doylestown, in the county of Bucks and State ofPennsylvania, have invented certain new and useful ImprovementsinPen-'Wipers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawing, and to the figures of referencemarked thereon, which forms a part of this specification.

My invention relates to that class of penwipers wherein the wiper issupported upon standards, which standards also act as a penrack by meansof hooks placed in their edges.

The object of my invention is'to produce a device which will be moreefiective in wiping pens and which will last much longer than thedevices hitherto used.

To this end my invention consists in the peculiar features andcombinations of parts more fully described hereinafter, and pointed outin the claims.

In the accompanying drawing the figure represents a top perspective Viewof my invention.

In the drawing the reference-figure 1 denotes a'base, upon the oppositeends of which are rigidly secured two vertical standards 2 and 3, havingtheir edges provided with hooks 4 for the reception ofpenholders.

My pen-wiper proper consists of a seriesof disks 5, made of felt orother absorbent material, placed side by side upon a shaft 6, whichshaft is journaled in bearings 7 in the top of the standards 2 and 3.Metal guards 8 are placed on either end of the shaft and on the insideof the standards to protect the felt disks 5 from being worn by contactwith the standards. On one end of the shaft is rigidly secured a wheel9, by means of which the disks and shaft may be turned in theirbearings. A wheel is used in the present instance; but it is evidentthat other equivalent means could be successfully used to turn theshaft. The other end of the shaft is provided with threads, whichreceive a thumb screw 10.

Serial No. 424,037. (No model.)

Placed between thethumb-nut and the standard is a washer 11, by means ofwhich the thumb-screw is prevented from wearing the face of thestandard.

When using my wiper, the pen is drawn across the felt disks 5 untiltheedge over which the pen has been drawn is coveredwith ink. When such isthe case, it is very hard to clean a pen, and I then loosen thethumb-screw 10 and revolve the wheel 9 until a clean edge is presented,when I again tighten the screw 10, which holds the shaft and disks in arigid position. In this way my pen-wiper will last a much longer timethan others that have been man ufactured, and when the edges of thedisks are completely covered with ink they may be removed and fresh onesplaced on' the shaft, when it is again ready for use.

This wiper can be made at an exceedingly 'low cost, and at the same timepresent an atand means, substantially as described, for

turning the shaft, as specified.

3. In a pen-wiper, a series of disks mounted upon a shaft, incombination with vertical standards, upon which the shaft is journaled,and a thumb-screw and washer for rigidly securing the shaft to thestandards, in the manner substantially as described.

4:. The combination, in a pen-wiper, of a se ries of absorbent disksplaced upon a shaft which is journaled in vertical standards, a wheelupon one end of said shaft, whereby the shaft and disks can be revolved,metal guards placed between the inner face of the standards and thedisks, and a thumb-screw and washer upon the opposite end of the shaft,In testimony whereof I affix m y signature in whereby the shaft is maderigid with the standpresence of two witnesses.

ards, all arranged and adapted to operate in T 7 the mannersubstantially as described. JOHN DU hols 5. The herein-describedpen-wiper, pro- \Vitnesses:
